First thanks for the cuttles Daniel they arrived not hatched so I'm just waiting,Now I'm interested in confirming my suspicions I have two koralia 3's in my 55gal are those going to be dangerous for the cuttles and if so what power heads do you recommend?

Any power head that you cannot cover the intake with foam is dangerous for cuttles, specially small ones.

You can cover the intake of any of them with foam - like you would use with an aquaclear hang on back filter. Good amount of current is subjective, so I can't really help you there. There may even be a way to cover the intake area of the koralia, but you would have to play with that.

If it's possible for you to drill a closed loop in, that would be the best option, I personally never plan on, nor will put a ceph in a tank with powerheads just because of the possible danger, it's not worth it IMO. Also, it would be very easy for you to just set up some plumbing for a hang-over closed loop. No drilling or anything, just pvc and a pump, not expensive, and not as much of a risk to cephs.

It seems that a closed loop would present most of the same dangers as a powerhead would. In either case, the intake must be ceph proofed. What do you see as the difference between the two?

It's waaay easier to cover up and keep unwanted things from going down. Also, even if you were able to cover up the intake on a powerhead, an extra curious octo could end up putting its arms in the output too far... I just think closed loops are way easier to keep stuff from going down, and, as an added bonus, are more aesthetically pleasing, as in some cases, you can't even see it, and in others, it's easy to camoflauge as apposed to a big black box in the aquarium...

just my :twocents:

Nope, I just don't see how covering the intake of a closed loop is any easier than covering the intake of most powerheads.
